The induced electric field in a region of time-varying magnetic field does NOT depend on the source of the variation, such as a moving magnet or a variable current in an electromagnet, but only on the rate of variation of the flux through the region.

Question

Quizplus · Accepted Answer

The induced electric field in a region of time-varying magnetic field depends solely on the rate of change of magnetic flux through that region, according to Faraday's law of electromagnetic induction, regardless of the source of the magnetic field variation.
